Record number: 1, Textual support number: 1 DEF
Any discontinuity in chromosome structure occurring across the entire cross-section of the chromosome; chromosome breaks are either of spontaneous occurrence or are produced by the action of mutagens. They are recognizable during nuclear division (mitosis, meiosis) and lead to the formation of centric and acentric fragments. 2, record 1, English, - chromosome%20break
Record number: 1, Textual support number: 1 OBS
Discontinuities which involve only one of the two chromatids or subunits of the chromatids are referred to as chromatid and subchromatid breaks. 2, record 1, English, - chromosome%20break

Les aberrations de structure sont la conséquence de cassures chromosomiques. Une cassure unique provoque la perte d’un fragment chromosomique : il y a délétion. Un cassure double sur un même chromosome peut entraîner la formation d’un chromosome en anneau qui résulte d’une cassure à chaque extrémité du chromosome suivie par la soudure des deux surfaces de section; ce chromosome en anneau équivaut à une double délétion. Si la cassure double intéresse deux chromosomes différents, les fragments rompus peuvent se recoller après échange réciproque et reconstituer des structures nouvelles : c'est une translocation. 1, record 1, French, - cassure%20chromosomique

Phenomenon which brings about a loss of chromosome material, i.e. a structural modification without any change in the quantity of this material. Breaks may also lead to complex rearrangements. 1, record 2, English, - breakage
Record number: 2, Textual support number: 1 CONT
(Specification of chromosome rearrangements) The only exception to this rule involves certain three-break rearrangements in which part of one chromosome is inserted at a point of breakage in another chromosome. 1, record 2, English, - breakage

Phénomène qui a pour conséquence soit une perte de matériel chromosomique, soit une modification de structure sans que la quantité de matériel soit changée. Les cassures peuvent enfin donner des remaniements complexes. 1, record 2, French, - cassure

(Modification intra-chromosique) Il arrive qu'après une cassure, un fragment de chromosome soit éliminé; il en résulte un raccourcissement d’un bras chromosomique. 1, record 2, French, - cassure

A deletion resulting in the formation of an acentric and a centric fragment of chromosome. 1, record 3, English, - terminal%20deletion
Record number: 3, Textual support number: 1 CONT
(Autosomal structural rearrangements). A good example of this is the deleted B group chromosome resulting in the cri du chat. This could arise by at least four different mechanisms which are terminal deletion, interstitial deletion, translocation, and unequal chromatid intrachange, and there are at least eight families in which the mechanism has been shown to be a reciprocal translocation. 1, record 3, English, - terminal%20deletion
